QA/G-4 provides non-mandatory guidance on developing Data Quality Objectives (DQOs) using a systematic planning process based on the graded approach. The guidance presents a step-by-step description of the DQO process. The Aug 2000 version supercedes the Sept 1994 version.

QA/R-5 defines the requirements and specifications for QA Project Plans (QAPPs) prepared for activities conducted by or funded by EPA. This document has been finalized and replaces QAMS-005/80. R-5 parallels the implementation requirements for QAPPs contained in the EPA Quality Manual for Environmental Programs (EPA Order 5360, July 1998), an internal policy manual.

QA/G-5 provides guidance on developing Quality Assurance Project Plans (QAPPs) that will meet EPA expectations and requirements. This document provides a linkage between the DQO process and the QAPP. It contains tips, advice, and case studies to help users develop improved QAPPs.

Requirements Documents (identified as QA/R-x) will also be the subject of chapters in the EPA Quality Manual for Environmental Programs. The Quality Manual requirements will apply to EPA Program Offices, Regions, and ORD laboratories. The QA/R-x versions will apply to EPA contractors and organizations receiving financial assistance from EPA (e.g., grants, cooperative agreements, and inter-agency agreements). They also will be issued as policy documents under the signature of the AA/OEI.

Guidance Documents (identified as QA/G-x) will be published as OEI reports after the appropriate peer and policy reviews and issued under the signature of the AA/OEI.
